When did you first start playing the game Metroid, and when did you last play? This one has been around for 25 years or so, and has been ported through a number of platforms (all Nintendo flavored). But if you are planning to go for the upcoming Metroid: Other M, you will probably need to refresh yourself on the back story. In the first video, Samus Aran (the heroine) brings you up to speed on the history, while in the second you get a trailer of the new game. Thanks to Kotaku for the heads up on this one.
